The distance to the town is not really what one would call walking distance, but IIRC there is a shuttle bus. There is a shuttle bus to Nelson too. It travels trough some beautiful scenery, however not knowing the time table I'm not sure you can make it to Nelson and back in time.
As far as the cancellations are concerned, you should be fine. I had some cancelled flights to Cancelgar, but it was in fall. July is OK.
Should you hire a cab, ask the driver to take to HWY3 towards Creston. From the turns just above the town you can take pictures of the runway that look like you're on short final.
From Google Maps, it looks like part of the town (not downtown) is just on the other side of the bridge next to the airport so that may be relatively easy to walk to.
